What is a major cultural event celebrated in Quebec?

The Carnaval de Québec is one of the largest and most famous winter festivals in the world, celebrated annually in Quebec City. This vibrant event showcases the unique culture and traditions of the region, featuring a wide variety of activities such as parades, ice sculptures, and musical performances. It brings together thousands of visitors from across Canada and around the globe, highlighting Quebec's rich heritage. The festival is a celebration of winter, community spirit, and camaraderie, making it a significant cultural event for the people of Quebec.

In contrast, the other options represent events that take place in different regions or are unrelated to Quebec culture. The Festival de Cannes is a prestigious film festival held in France, Oktoberfest is a famous beer festival in Germany, and the Calgary Stampede is an iconic rodeo and exhibition held in Alberta. Each of these events has its unique cultural significance but does not specifically celebrate the heritage and traditions of Quebec, making the Carnaval de Québec the clear choice in this context.
